Do you like taking photos?
Yes, I do. I really like taking photos, especially when I travel to a new place and see some beautiful scenery.
What do you usually take photos of?
I usually take photos of beautiful scenery. If I see something funny in the street, like a small animal, a pet, or a beautiful cloud, I also take a picture of it.
Do you prefer taking photos with a phone or with a camera?
I prefer taking photos with my phone because I do not carry a camera with me all the time. Cameras can be heavy and expensive, but I have my phone on me all the time, so it is more convenient.
Do you keep old photos?
Yes, I do. I think different photos have special meanings, and each photo can show a special experience. I hardly ever delete old photos because they help me remember some interesting memories.
Do you like taking photos when you travel?
Yes, I enjoy taking photos when I travel. First of all, I enjoy beautiful scenery, so I want to keep it on my phone. Also, I like keeping old memories.
Did you like science when you were young?
Yes, I did. I think science is an interesting subject, and I especially like earth science.
Why are you interested in Geography or Science?
I am interested in earth science because my parents influenced me. Also, I met a great teacher when I was in primary school, and he taught me geography.
Do you like visiting museums?
Yes, I do. I really like going to geography museums, and sometimes I can stay in a museum for a whole day.
Would you like to study Earth science in university?
Yes, I would. My dream is to study Earth sciences in a British university, and that is one reason why I am preparing for the IELTS test.
Talk about a photo you have taken.
Today, let me tell you about my favorite photo. I took this photo two years ago in my high school. I took it from my dorm room window, and in the photo I can see the whole school campus.
My high school is not very big, but we have everything we need. In the photo, there are two large buildings, five basketball courts, a soccer field, and running tracks. The school is surrounded by mountains and a beautiful lake, so it is a very beautiful place. The air also looks fresh. If I look closely, I can even see some schoolmates playing basketball on the basketball court.
I took this photo with a Canon digital camera. Cell phones were not allowed on campus, so sometimes I took my camera with me to school because I enjoyed taking photos. The camera was a birthday present from my dad, and he loves photography.
I still have this photo on my computer. When I open it and look at it, it reminds me of the good time when I was in school.
Why do people take photos when they travel?
People take photos when they travel because people do not have perfect memories. We are not computers, so we cannot remember everything in the past. When we take a photo, we have a record of something. Later, we can look back at the photo, and it can remind us of the place, the people, and the experience. Photos are also more vivid than writing.
Do people take too many photos nowadays?
Yes, I think people take too many photos nowadays. Many people take lots of photos and believe they will look at them later. However, in reality, these photos are just stored in their mobile phones or computers, and many people never look at them again.
How have smartphones changed photography?
Smartphones have changed photography a lot. At first, the mobile phone was just a communication tool, and people did not usually use it to take photos. But recently, the camera technology in mobile phones has developed. The picture quality of photos taken by mobile phones is much better now, so more people use mobile phones to take photos.
